Specification of Letters Patent.

To all whom it may concern:

Be it known that I, ROBERT G. CLYNE, a subject of the King of GreatBritain, residing at Alton, in the county of Madison and State ofIllinois, have invented certain new and useful Improvements inCartridges, of which the following is a specification.

My invention relates to improvements in cartridges, and moreparticularly to metallic base caps for securing and anchoring the papershell or tube' of that class of cartridges known as paper shot shellsThe primary object is to improve upon and reduce the cost of thematerial entering into a metallic base cap of this class, and at thesame time give it greater strength and providing against rust oroxidation as is done where the entire cap is made of a nonferrous metal,such as copper, brass, or the like.

A further object is to provide a double walled or laminated metallicbase cap, the inner wall or shell being preferably made from ferrousmetal, such as iron, steel, or the like, and the outer wall or shellbeing made of a thin layer or covering of nonferrous material, thisouter Wall being of comparatively thin material but of sufiicientthickness to exclude the air from coming into contact with the inner orthicker shell of ferrous material thereby preventing rusting oroxidation.

A still further object is to provide an improved form of metallic basecap having its mouth or rim portion reinforced by means of an inwardlyextending hooked beading formed about the upper marginal edges of theouter shell or covering and extending over and interlocking with theupper marginal edges of the inner shell or main body portion composed ofthe ferrous metal.

With the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement, and combination of parts,hereinafter described, illustrated in some of its embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims.

Referring to the drawings forming a part of this specification, Figurel, is a sideelevation of the cartridge constructed in accordance with myinvention, a portion of the improved metallic base cap being broken awayand shown in section for the purpose of clearer illustration of theparts.

PatenteolMay e. 1913..

The improved metallicbase cap to which this invention particularlyrelates, comprises 7 a double-walled or laminated base cap, the main orinner wall or shell 3, being composed of suitable ferrous metal, such asiron, steel, or the like, and the outer shell or covering 4, being ofnonferrous metal, such as copper, brass, or the like, this outercovering or casing being preferably of relatively thin material, but ofsufficient thickness to exclude the air from the main wall or shell 3,and thereby preventing the rusting or oxidation of this part of the basecap.

The outer shell or covering 4, is preferably provided about its uppermarginal edges with an inwardly extending hooked heading 4, extendingover and interlocking with the upper marginal edges of the inner wall orshell 3, thereby not only reinforcing and strengthening the mouth of themetallic base cap and forming an interlocking anchor heading forinterlocking with the subjacent portion of the paper shell or tubal, butalso sealing the rim portions of the inner and outer walls and therebyexcluding the air from between the walls and preventing any rusting oroxidation at the rim portions of the base cap.

The improved metallic base cap may be.

provided with the usual peripheral base flange 4, for holding thecartridge in position within the breach of the gun barrel, and the baseor bottom portion thereof may be provided with a battery cup receivingopening or primer pocket 5, of any suitable and convenient form for thereception of a suitable primer or a battery cup 6, such as shown, forexample,-1n Fig. 1, of the drawmgs. 4

From the foregoing description, taken-in connection with theaccompanying drawings,

the construction and advantages of my inventionwill be readilyunderstood.

Having thus described some of the em- -ferrous metals,respectively,,said outer shell bodiments of my invention, what I claimhaving an annular hooked flange taking over and desire tosecureby'Letters Patent is,- and en aging the rim portion of said in- 1.
